Trains to Jaipur leave a station every 45 minutes. At the counter, a passenger is told that the last train left 20 minutes ago and that the next one will leave at 3:15 p.m. At what time was the passenger told this?
Answer & explanation
Correct answer: option 1
The correct answer is Option (1) → 2:50 p.m.
Two trains in a row are 45 minutes apart. Find when the last train left, then add the 20 minutes since it left.
Next train at 3:15 p.m., so the last train left at 3:15 p.m. \(-\) 45 minutes \(=\) 2:30 p.m.
It left 20 minutes ago, so the time now is 2:30 p.m. \(+\) 20 minutes \(=\) 2:50 p.m.
Check: from 2:50 p.m. the next train is 25 minutes away, and \(20+25=45\) minutes
